' a citizen of the Republic of France, resident 'ofPar-is, France, have inventednew and useful Improvements fill Mountain-Guns, which invention is fully set" forth in the following specification. w

This invention has for its object top'rovide an improved mountaingun o fthe type comprising a gun barrel, a" breech-carrying sleeve and a gun sli'de,-'all capableof being separated from" one anoth'erfor transport.

The improved gun is cha acterizedby the feature that the simultaneous assemblage of the'breech-ca'rrying sleeve with the gun slide and with the gunbarrel that'haspreviously "been fastened upon the latter, is efl'eeted'hy 'a direct rotation of the saidsleeve, this operation' serving at thesame time to 'kee one of the elements of the firingmje'ch'anism in: its inoperative position until' the aforesaid assembla'ge has been completed. v Various practical constructions o f'thi's invention are illustrated by way of example in the accompanying drawings in which z Figure l is a longitudinal'elfevation partly in section of acon'stru'ctional form of this invention.

'Fig s.;2 and 3 are sections on the lines 2'2 an'd'3'3"respectively of F ig.- I.

In these figures, the gun barrel is shown fastened upon the gun slide, the 'breeeh-carrying sleeve being engaged on the gun 'barrel in the position it occupies before ith'a's been rotated for elieoting its simultaneous assemblage withthe gun barrel and the gun slide.

In order to assure the simultaneous assembl age between the breeclrcarrying sleeve B and the gun barrel A on theone hand, and between the said sleeve and the gun slide C on the other hand, the said sleeve'is rotated. The said sleeveis provided for this purpose with a handle E pivotally mounted on an axle pin 6 journaled in a block B projecting from the said sleeve.

For operating purpose, the. handle is turned up into the position shown inq full lines in Fig. 3,. and indicated in dot and dash lines inFi 6. .During the rotary movement the teeth or screwthreads,B of

At the end of the rotary movement' 'the handle E is turned down, thereby causing a heel E which is inclined relatively to the shank of the handle, to engage in a notch a of corresponding inclination provided in the gun barrel Aythis allows of completing the assemblage. The engagement of the" in-; clined heel E with the inclined sides" of the notch a efiects 'a'camming action that insures a tight seating of the sleeve in place.

When the assemblage has been completed and the sleeve seated, the finger G becomes entirely free, as shown in Figs. 14 and 15, and the rod G is freed so that it can be actuated for firing.
